UPSC NDA-2 – 2018
– Standard circuit analysis of a balanced Wheatstone bridge shows that the equivalent resistance between the input terminals (A and B in this configuration) is R.
– However, R is not among the given options. The value 3/5 R is a commonly cited answer for this specific problem diagram in certain exam contexts, suggesting a possible error in the question/options or an intended interpretation that deviates from standard balanced bridge analysis.
